Abstract: Thiourea-chitosan-copper (II) complex was prepared, characterized by FT-IR, UV-visible spectroscopy, XRD and TG-DTA. The antibacterial activities of chitosan, thiourea-chitosan and thiourea-chitosan-copper (II) complex against E. coli and S. aureus were investigated. Results showed that the antibacterial activity of thiourea-chitosan-copper (II) complex was obviously enhanced when compared with chitosan.

Key words: chitosan, thiourea-chitosan-Cu (II) complex, antibacterial activity
